Why are nitrogenous bases important?

• The number of adenines and cytosines determine the type of RNA produced

• The order of nitrogenous bases determines the order of amino acids in the protein made

• The amount of thymine and guanine in the DNA molecule determines the length of the genes.

• The type of hydrogen bonding between the nitrogen bases determines which amino acid will be added to the peptide chain.
